INIPROVEIWEN IN WASH-BOILER.

To all whom may concern:

Be it known that I, D. A. Pon'rEnrmLD, of New Pa1is,in the county ofPreble, and State of Ohio, have invented a new and useful Improvement inVJashfBoilers; and I do herebydeclare that the following is a fullandexact description thereof', reference being had to the accompanyingdrawing, making a part of this specification, in whichl Figure 1 isaview of the boiler,with a section removed, showin g the interior.

Figure 2 is the lid.

Figures 3 and 4 are spouts.

The same letters in the different figures refer to corresponding partsof the boiler.

M y invention relates to an 'improvement in washboilers, in which theboiling water is spouted above its level in the boiler, and pours backin streams, thus producing athorough circulation'of the water in theboiler, resulting in a rapid cleansing of the clothes by theboilingprocess. I

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawings. .f

A represents an ordinary wash-boiler.

C and C are spouts, (constructed of tin or other sheetmetal,) with theirbases resting on the bottom of the boiler.

The spouts C and C' are sufficient in size at their bases to maintainthem lin an upright position, and taper to the top, where they terminatein small tubes. The peculiar shape of the spouts is designed to requirethe least amount of room in the boiler, the por- Ntion or side adjacentto the end of the, boiler being 'rounded to conform in shape to saidend.

or without a cover on the boiler; and the peculiar shape of the spouts,as shown, also causes a partial vacuum within the base when the boileris in operation, by which said spouts are held rmly in their positions.

When the boiler is constructed with a drop-pit, the bottom edges ofspouts may be made uniform, as the depression in the boiler allows thewater to How be- 'neath the spouts, butwhen the bottom of the boiler isdat, a suiiicient space must be provided for admitting the Water, asshown at e, fig. 3.

d and d are valves in the boiler-lid, by which the steam is allowed toescape, thus preventing the water from boiling over the sides' of theboiler, without the necessity.of removing the lid.

Having thus fullydescribed my said invention,

What I claim, and desire to secure by Letters Patent is- Iii combinationwith the boiler, the conical or pyramidal spouts, as described, i. e.,their bases resting in the bottom of the boiler, Without theintervention of a horizontal partition, and so arrangedas to admit theSupply of Vwater by spanning the sunken pit, or by means of an openingat the bottom, as set forth.4
